Definitions

  • the present invention relates to trays for containing foods, such as prepared dishes.
  • the trays for containing food comprise a hollow container delimiting at least one cavity between a container bottom and a container side peripheral wall having at least two opposite first sides generally parallel to one another, with a main opening face defining a plan for opening the cavity upwards.
  • trays are generally made of plastics with relatively thick walls, that is to say with a relatively thick container bottom and relatively thick lateral peripheral wall.
  • the relatively large thickness of the walls of the trays is necessary to ensure sufficient stiffening of the trays so that they can be easily handled. and that they are not deformed by the foods they contain.
  • the side peripheral walls of the trays must be rigid enough to allow stacking trays without risking their degradation.
  • the main stiffening means used in these known trays is to provide that the walls of the trays have a thickness sufficient to prevent their deformations.
  • a thickness of 0.6 mm is usually suitable for molded or thermoformed plastic trays.
  • a further disadvantage of known trays is that the processing of plastics is very expensive. Thus, the larger the quantity of plastic material to be treated, the higher the cost of this treatment. This high cost of processing plastic packaging waste has a logical effect on the price that the consumer has to pay when he buys the food in the trays.
  • the trays for containing food include a generally plastic hollow container and an outer reinforcing structure having a bottom wall in close proximity to the container bottom and parallel side flaps two by two which are in close proximity to the respective outer faces of the container sides.
  • This second type of tray has the advantage of using a smaller amount of plastic, because the reinforcing structure improves the mechanical strength of the tray.
  • the wall of the hollow container may be thinner.
  • this second type of tray has a first drawback which is to require the addition of an additional element reported, namely the glue.
  • a second disadvantage is that the adhesive is a chemical substance that does not easily recycle and that can be harmful to the environment when it is burned for example during the treatment of waste.
  • the problem proposed by the present invention is to design a tray for containing food which, while being rigid enough to be transported and stacked, minimizes the environmental impact through a smaller amount of hard-to-recycle plastic waste generated by such a container compared to known trays.
  • the invention aims to facilitate, after use, the recycling of the materials constituting the tray.
  • the invention also facilitates the assembly of the tray without adding additional elements.
  • the invention provides the tray described in claim 1.
  • this tray as a combination of two elements, namely a hollow container and an external structure of reinforcement, allows to combine the mechanical and ecological properties of each element.
  • the hollow container may have less mechanical properties, and may therefore be formed of a thinner wall. Such a hollow container thus generates less waste and therefore has a lower environmental impact, even if it is made of material rather difficult to recycle such as plastic, suitable for being in contact with the contents of the tray.
  • the plastic material makes it possible, for example, to produce a hollow container that is waterproof and / or insensitive to moisture.
  • the reinforcing structure is designed to mechanically reinforce the hollow container by preventing the bottom of the container from sagging under the action of the weight of the food contained in the container, and by preventing sidewall bends during stacking.
  • the reinforcing structure is not in contact with the contents of the tray, and can therefore be made of a different material and more easily recyclable, for example cardboard.
  • the mechanical combination of the container bottom with the bottom wall increases the mechanical properties of the tray.
  • the tray will not sag under the weight of the food it contains.
  • the mechanical combination of the first two sides with the two first side flaps increases the mechanical properties of the tray.
  • the tray can be easily stacked.
  • the mechanical assembly of the hollow container and the reinforcing structure is provided by separable mechanical fastening means.
  • the hollow container is made of plastic, and that its thin wall has a thickness of between about 0.2 and 0.4 millimeters, preferably about 0.3 millimeters.
  • Plastics are easy and inexpensive to implement, in particular by thermoforming.
  • the trays of the prior art usually have a thickness of at least 0.6 millimeters, in the case of similar mechanical strengths.
  • the container of the invention uses a hollow container of thickness less than half.
  • the amount of waste generated by the tray of the invention is therefore about half as much.
  • the hollow container is of food plastic material.
  • the combination of the first assembly groove, the bosses, the first two lateral flaps and flaps constitutes said separable mechanical coupling means: the mechanical assembly of the two elements - hollow container and reinforcement structure - is effected by a kind of reversible snap.
  • the hollow container can be engaged by simple translation into the external reinforcing structure and is then retained in said structure by simple snapping.
  • the separation of the hollow container away from the reinforcement structure can be performed by sufficient traction between the two elements, which is a simple and fast operation, allowing selective sorting.
  • Such a hollow container design only requires a mold modification. No additional items such as glue should be added for assembly.
  • the manufacture of this hollow container is simple and technology (thermoforming or injection molding) to achieve it is known, widespread and inexpensive.
  • the absence of glue facilitates and improves the recycling of materials.
  • the first two sides each comprise at least two disjointed bosses positioned near the longitudinal ends of the first two sides.
  • the at least one boss has an oblong shape whose major axis is substantially parallel to the main opening face and has a length of about 2 centimeters.
  • This configuration allows the assembly between the hollow container and the reinforcement structure to be made over a greater length. Thanks to a better distribution of forces, the assembly is mechanically efficient and reliable.
  • the four sides of the tray comprise upper radial facets substantially coplanar and defining a lidding surface.
  • Lidding is a simple and inexpensive method of closing a cavity. It consists in gluing a plastic film on a peripheral cavity surface. It allows a better conservation of the food contained in a tray, and it is a privileged space of communication with the consumers.
  • the hollow container is made in one piece, by thermoforming a sheet of thermoformable material of about 0.3 millimeters thick, or by injection molding.
  • thermoforming and injection molding are well known and inexpensive.
  • the external reinforcing structure is made of cardboard.
  • the cardboard is inexpensive and easy to implement. It has good mechanical properties. It is easy to cut and fold. It has good properties for recycling.
  • the external reinforcing structure is made by cutting a strip of sheet material and folding along transverse fold lines into four successive sections each forming one of the four lateral flaps, each section having an edge. lateral to longitudinal fold line to form a flap and having the other lateral side with longitudinal fold line to form a portion of the bottom wall.
  • This configuration is simple to perform. It is thus easy to form by simple folding and bonding steps an external reinforcing structure which is mechanically very strong.
  • the transverse fold lines are divergent.
  • This configuration makes it easy to obtain oblique lateral flaps.
  • the hollow container 1 comprises a cavity 2 bounded by a container bottom 3 and a container side peripheral wall 4 forming two opposite first sides 5a and 5b and two opposite second sides 15a and 15b.
  • the cavity 2 is open upwards according to an opening face 7.
  • the lateral peripheral container wall 4 of the hollow container 1 has a slight clearance ⁇ ( figure 4 ), allowing the stacking of superposed hollow containers.
  • the hollow container 1 has a substantially rectangular shape whose four corners are substantially rounded. It is made of thermoformed plastic material, from a plate whose thickness is about 0.2 to 0.4 millimeters, advantageously about 0.3 millimeters.
  • the first two opposite sides 5a and 5b of hollow container 1 each comprise, near their opening edges 6a and 6b, a first upper radial facet 9 which expands outwards and is extended by a first descending lip 10 to constitute a first assembly groove 11 open downwards.

These bosses 8a are located near the longitudinal ends such as the ends 105a and 205a of the first two opposite sides 5a and 5b of the hollow container 1, and away from the opening edges 6a and 6b.
  • each boss 8a is disjoint and each boss 8a has an oblong shape whose major axis is substantially parallel to the main opening face 7 and has a length of about 2 centimeters, for a tray of about 15 centimeters in length, 10 centimeters wide and 3 centimeters high.
